Offroad
A very sturdy gearbox optimized for harsh off-road conditions, sacrificing fuel efficiency, top speed and gear count in exchange for three Low Gear stages.
Gb-8V 2600TTA
A more powerful alternative to regular stock power systems, this engine offers increased power, durability and acceleration at the cost of fuel consumption.
Gb-8V 2700T
A fine-tuned version of a popular engine sporting excellent reliability and power at the cost of even lower fuel efficiency.
Highrange
A high-range gearbox variant with increased gear count and top speed, and an additional High Gear at the cost of lower durability.
Fine-tune
A specialized gearbox allowing free Low Gear / R Gear transfer ratio tuning. Notoriously fragile and not very fuel-efficient in AWD mode owing to its mechanical complexity.
